Hello,
My goal is: epvpImg: My paint skills are bad![^]

What I have tried:

I want multiple boxes with Read more / Read less function. I am able to create one working box but when adding more it doesn’t work. I am not that experienced.

What i have:
https://codepen.io/flo44781/pen/agZWwo -> One working Box with Read more / Read less

When i add new boxes do i need to to re write the Java Script for every new box i do?
Can i say the script that it only affect box-1 another script should only affect box-2 …

Best regards,
Florian

just use

parentElement

and

childNodes

in javascript for dynamic event. In your button click event use

JavaScript

this

in your function or try the below answer. Use unique id for button

JavaScript

function myFunction(btn_id) {
  
  var btnText = document.getElementById(btn_id.id);
  var parentElem = btn_id.parentElement;
  var childElemP = parentElem.childNodes;
  var spanElem = childElemP[1].childNodes;
  
  if (spanElem[1].style.display === "none") {
    spanElem[1].style.display = "inline";
    btnText.innerHTML = "Read more"; 
    spanElem[2].style.display = "none";
  } else {
    spanElem[1].style.display = "none";
    btnText.innerHTML = "Read less"; 
    spanElem[2].style.display = "inline";
  }
}
